Power cord upgrade

Also, OP…don’t buy the puritan ultimate cord without ability to return it. I tried it, gave it few weeks of break in and sold it. It was harsh, thin and fatiguing in my system with all pass labs amplification at the time. I eventually got rid of psm 156 as I found it to be an overall bad fit for my system and I only ran source components off the puritan. 
good luck

Using the Shunyata Denali 6000 v2 I have had great success with both the Shunyata Sigma v 2 and Kubala Sosna Elation power cables.

I’ve been impressed by reviews of some direct sellers that are worth exploring as they offer high value and generous free trials.  On the lower end there’s the Ice Age OFC “Frankencable” and on the pricier side there’s the Snake River Signature both of which seem to punch well above their respective price points.  Best of luck.

I’d recommend a Transparent Reference. That is what I have on my system components with a Hurricane on my power amp.

@skids: I tried an AudioQuest Hurricane source, and a AQ Hurricane high current (along with various other AQ PCs) power cable in my audio system on different components, and after much trail and error, and out of all the AQ power cables I tried, I ended up using an AQ Hurricane high current PC on my AQ Niagara 3000 power conditioner only. I absolutely love the AQ Hurricane HC power cord on my power conditioner, which it will remain for the foreseeable future. As far as AudioQuest power cables are concerned, I found only their upper tier power cables to be to my liking, as I also use an AQ Firebird source power cable on my streaming DAC.  A totally phenomenal AQ Firebird source power cable, although very expensive, would work wonders on your streamer.  Otherwise, you’ll just have to keep on experimenting with different power cables until you find the right one. Happy listening.
